How New Hampshire's Primary Works

New Hampshire uses a Semi-Closed Primary system

⚖
Semi-Closed Primary
Registered party members vote in their own party's primary. Unaffiliated voters may choose a party primary to participate in, but voters registered with a different party cannot cross over.
How It Works
If you're registered Democrat, you vote in the Democratic primary. If you're registered Republican, you vote in the Republican primary. If you're unaffiliated, you can pick either; you may need to formally affiliate at the polls.
IVP's Position
An improvement over closed primaries, but still ties the system to party labels. Voters shouldn't have to join a private organization to participate in publicly funded elections.
